Electron beam has a wide range of applications in the material processing and joining techniques. Apart from that, it has also been utilized to simulate steady as well as transient fusion reactor relevant heat loads. Transient heat load events spontaneously occur in the fusion reactor. Several hundred megawatt of power is dumped upon the plasma facing material surfaces for a very short ...

Introduction: Lithium-ion batteries are widely used as power sources for portable electronic devices (laptop, phones, and players) and electric cars due to their high energy density. New applications, such as Formula E, require also a huge power capability that the iron-phosphate-based positive electrode is able to provide. Indeed, a recent publication  shows that, at the particle level (20 ...

In this paper simulation and parametric study of a PDMS valveless micropump using Fluid-Structure Interaction (FSI) appraoch is presented. The simulation for the valveless micropump were carried out in COMSOL Multiphysics software. In case of a valveless micropump diffuser/nozzle element is connected to a chamber with an oscillating diaphragm. To improve the flow rate of the valveless micropump, ...

Solder connections are one of the most essential parts of the PCBs. Despite many well-known scientific works that have been done about overlap solder interconnection properties, such as fracture, fatigue and reliability studies, little attention have been given to the investigation of the connection between effects of electrical properties and laboratory soldering shortages such as effects of ...

Micro electrical discharge machining (MEDM), a scaled down version of EDM process, is a micro machining process used to fabricate micro holes and intricate shapes in electrically conductive materials irrespective of its hardness. In this process, an electric spark is generated in the gap between the two electrodes (tool as cathode and workpiece as anode) submerged in dielectric that leads to a ...
